Cooking measurement converter
Convert common kitchen volume, weight and temperature units without pretending that a cup of every ingredient weighs the same.
Batch recipe unit converter
Paste several ingredient lines. FOOGG changes recognized leading measurements and leaves the rest of each line intact, so you can convert a recipe in one pass instead of one number at a time.
Ingredient-specific cups ↔ grams converter
A cup-to-gram result is only honest when it uses a reference for the exact ingredient and measuring method. Enter grams per US cup from the package, a trusted recipe source or your own weighed cup.
What this cooking converter handles
Choose Volume for US customary cups, tablespoons, teaspoons, fluid ounces, pints and quarts plus milliliters and liters. Choose Weight for grams, kilograms, ounces and pounds. Choose Temperature for Celsius, Fahrenheit and Kelvin.

NIST practical kitchen reference
The U.S. National Institute of Standards and Technology publishes rounded household equivalents for everyday cooking. These are intentionally practical approximations, not replacements for the more precise conversion factors used by FOOGG’s calculator.
| US customary measure | NIST household metric equivalent |
|---|---|
| 1/4 teaspoon | 1.25 mL |
| 1/2 teaspoon | 2.5 mL |
| 1 teaspoon | 5 mL |
| 1 tablespoon (1/2 fl oz) | 15 mL |
| 1 fluid ounce | 30 mL |
| 1/4 cup | 60 mL |
| 1/3 cup | 80 mL |
| 1/2 cup | 120 mL |
| 3/4 cup | 180 mL |
| 1 cup | 240 mL |
| 1 pint (2 cups) | 480 mL |
| 1 quart (4 cups) | 950 mL |
| 1/2 gallon (8 cups) | 1.95 L |
| 1 gallon (16 cups) | 3.84 L |
| 1 ounce by weight | 28 g |
| 1/4 pound (4 oz) | 114 g |
| 1 pound (16 oz) | 454 g |
Source checked September 24, 2026: NIST Metric Kitchen — Cooking Measurement Equivalencies. NIST marks these household values as approximate. For example, its practical 1-cup value is 240 mL, while FOOGG’s US-customary calculator uses approximately 236.588 mL.
Why FOOGG does not guess cups-to-grams
A cup measures volume; a gram measures mass. One cup of flour, sugar, butter and water do not weigh the same, and packing method changes the result too. A converter that turns any cup into one fixed gram value would be misleading. Use the ingredient-specific converter above when you have a grams-per-cup reference for the exact ingredient and measuring method. It applies your reference without pretending it fits every ingredient.
US cups vs metric cups
This tool labels its cup, tablespoon, teaspoon, fluid ounce, pint and quart values as US customary. A metric cup is commonly 250 mL, so do not silently substitute one standard for the other when following an international recipe.
Conversion standards and precision
FOOGG uses U.S. customary conversion factors for cups, tablespoons, teaspoons, fluid ounces, pints and quarts, and standard avoirdupois factors for ounces and pounds. Batch results are rounded for kitchen readability; use the single-value converter when you want to inspect one conversion more closely. The practical household table above is independently source-checked against NIST’s Metric Kitchen; see the methodology and sources for the calculator factors used by FOOGG.
Scaling and converting are different jobs
If you need to change a recipe from 4 servings to 7, use the recipe scaler first. Then convert any resulting units here. If one ingredient is limiting the batch, use Scale by One Ingredient.
Cooking conversion questions
How many milliliters are in one US cup?
One US customary cup is approximately 236.588 mL. A metric cup is commonly 250 mL, which is why the standard matters.
Can I convert cups directly to grams?
Not generically. Cups measure volume and grams measure mass. If you have a grams-per-US-cup reference for the exact ingredient and measuring method, use the ingredient-specific converter above.
How do I convert Fahrenheit to Celsius?
Subtract 32 from the Fahrenheit value, then multiply by 5/9. The converter does that automatically.
